BITCH GATE.

Application led September 6, 1921. Serial No. 498,757.

.70 all whom t may concern.' Y

Be it known that I, PRESTON Roors, a citizen of the United States,residing at San Benito, in the county of Cameron and State of-TeXas,have invented new and useful Improvements in Ditch Gates, of which thefollowing is a specification.'

This invention relates to a gate for irrigation systems, the generalobject ofthe invention beingto provide a gate which will be leak proofwhen enclosed so asto prevent waste of water from the irrigation system.Y

Another object of the invention is to provide means for locking the gatein either its open or closed position so that it cannot be moved by anunauthorized person after being adjusted.

A further object of the invention is to provide means for moving thegate laterally towards and away from the opening in the wall so that itwill make a tight fit with the wall around the opening when movedinwardly and will be free of said wall when moved outardly, thuspermitting the gate to be raised and lowered very easily.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, andin which Figure 1is a diagrammatic plan view showing a portion of an irrigation systemwith my invention in use. Y

Figure 2 is an enlarged front view of part of a head wall with my gatethereon.

Figure 3 is a'horizontal view on line 3-3 of Figure 2. Y

Figure 4 is a vertical section on line 4--4 of Figure 2.

Figure 5 is a vertical section with the gate 1n raised position.

Figures 6 and 7 are detail views.

In these views 1 indicates a portion of one of the lateral ditches ofthe system, in one bank of which is located the head wall 2, preferablymade of cement and which contains the pipe 3 for permitting some of thewater to escape from the lateral ditch into the small ditch 4 whichleads-the water t0 the parts of the farm to be irrigated. My improvedgate for controlling the flow of water through the pipe is shown at 5.This gate is provided upon its front face with the bearings 6 in whichare rotatably mounted the shafts 7, the ends of the shafts being iushwith the side edges of the gate but said ends are provided witheccentric projections 8 which engage the grooves 9 in the gate Vguides10. These guides are formed of beams which are bolted to the head walland strips 11, preferably of wood are placed around the opening or theend of the pipe inthe Wall to make a tight iit with the gate. Thesestrips may be screwed to other strips 12 which are embedded in the walland bolted thereto. A gasket 13 may be suitably secured to the outerfaces of the strips 11 to insure a tight t of the gate.

It will be seen that when theA shafts 7 are rocked the position of theprojections will be changed so that the gate will be moved inwardly oroutwardly according to the direction of rotation of the shafts. Thus thegate can be forced against the strips to tightly close the opening or itcan be moved in an opposite direction so that the gate can be raised andlowered easily as in this posii tion the gate will not touch the stripson the gasket.

The gate is provided with an extension 14 at its upper end to which issecured the segments 15 between which the lever 16 is pivoted. Holes 17are formed adjacent the curved edges of the segments for receiving a pinfor holding the lever in adjusted position. One end of the pin isprovided with a hole for receiving a lock 18 so that the pin can belocked in position. Each shaft 7 is provided with an arm 19 which iscarried by a collar 20 on the shaft. The outer face of the gate isgrooved, as at 21, to receive these collars. The two arms are connectedtogether by the links 22 and the upper arm is connected with the leverby the link 23. This extension is also provided with a handle bar 24 forraising and lowering the gate.

It will thus be seen that when the gate is in lowered position and thelever is swung upwardly the shafts will be rocked to place theprojections in Such a position that the gate will be moved inwardlyagainst the gasket on the stripsto make a leak proof closure for theopening in the wall so that no water can escape through said opening.

rIhen when itv is desired to raise the gate the lever is swung outwardlyandvdownwardly so that the shafts are turned to cause their projectionsto 'force the gate* outwardly and thus the gate can be moved Withoutinterference on the part of the strips aroundthe opening.

This gate Will prevent leakage. and thus waste of water from the systemand is very easily operatedand canbemanufacturedto sell at low cost. Itis; simply necessary to make the gate large enough to cover the opening.It can also be easily substituted for a new one if it; should get out oforder. The lever can either be locked in itsA raised or lowered positionso as to lock the gate in its` adjustedposition thus preventinganunauthorized person from tampering with the gate.

It is thought from the foregoing description that the advantages andnovel features of my invention will be readily apparent.`

desire it to be understood; that lii may make changes in theconstruction and in the combination and arrangement of the severalparts, provided that suchchanges fall Withinthe scope of the appendedclaim.

Whatl Claimisif- A water gate of the class described comprising a frame,guidevvays thereon, a gate slidably mounted between the guideways, apair-of" shafts rotatably mounted on the gate and having eccentricprojections on their ends engaging the` guideways, an arm on each shaftalink connecting the arms together, an extension on the upper end of thegate havingy a handle formed therewith, segments onthe extension havingholes therein, a lever pivoted between the segments, a link connectingthe lever with the arm ofVl the upper shaft, a pin adapted to be passedthroughv any pair of holes in the segmentsv 'and through the lever tohold the parts in adjusted position anda lock, for holding-the pin inplace.-

In testimony whereof I aix my signature.

PRESTON ROOTS.
